first thanks to all the people that respond to all my questions. my new question is. there seems to be a lot of moisture in the compartments under the coach. i never had this problem in my class a . moisture seems to collect in the shallow ones and not the lage ones. i live in mass very near the ocean. we have free-zzing temps at night and warm up to 40-45 during the day. some compartments have plug holes in them, should i open them. new to a class c with sealed compartments

How much moisture is a lot of moisture? I had one compartment behind the rear wheels with quite a bit of water in the bottom once. After shining a light in the wheel well, I could see light through a slight crack in the sealant. As for the other bays, never had any water issues. On some, if you don't secure the center lock on the hatch, it might leak a little in the rain or traveling in the rain. Which model do you have? The heat in ours is ducted into the bays around the water tanks and black / gray dumps. Not sure how much that would matter, but that's only 2 bays.
